Origin

This is an independent usage of the suffix -phobia (via Latin from Greek) meaning ‘fear’. In modern times psychologists have ransacked the Greek and Latin languages to find ever more words to combine with phobia as new fears have been uncovered. These include brontophobia (early 20th century),‘fear of thunder’ formed from Greek bronte ‘thunder’ also found in brontosaurus (late 19th century) literally ‘thunder lizard’; heliophobia (late 19th century) formed from helios Greek for ‘sun’, also found in heliotrope (Old English) for a plant that turns its flowers to follow the sun; and among the most recent nomophobia, a joking coinage of 2008 for those who feel anxious if they have no mobile phone.
